Digi-Key offers many products in full manufacturer tape and reel quantities as well as smaller quantities for prototyping and engineering purposes. To help identify how you will get your parts Digi-Key has added internal suffixes. For this example I will use Microchip Technology part ATTINY88-MUR.
ATTINY88-MURTR-ND - "TR" stands for full manufacturer tape and reel. In this instance, it would be a 6,000 piece reel.
ATTINY88-MURCT-ND - "CT" stands for cut tape. Digi-Key will take the full manufacturer reel and cut off a strip of parts based on the quantity that the customer orders.
NOTE Digi-Key tries to ship in one strip when possible however, if you require your order to be one continuous strip, this should be requested at the time you place your order.
ATTINY88-MURDKR-ND - "DKR" stands for Digi-Reel. This is a Digi-Key custom service where we attach an 18 inch leader and trailer to a standard cut tape strip and wind it on a new reel . This gives customers an option to order quantities in less than full manufactures standard packages and retain a streamlined process for pick and place assembly. Digi-Key offers Digi-Reels in 8mm, 12mm, 16mm, 24mm, 32mm, 44mm, and 56mm widths. The leader and trailer for the Digi-Reel will match the original tape width.
NOTE A $7.00 reeling fee will be applied to each reel ordered. Digi-Reels are a custom product and are non-cancelable and non-returnable.
"ND" once stood for "No Discount" back when the paper catalog displayed a listing of discount percentages based on quantity. Today, "ND" has become a Digi-Key signature allowing people to know that a listed part number is available at Digi-Key. Many times the part numbers are the manufacturer's part number with a simple -ND added to the end.
